Embodiment Construction

[0024] Embodiment 1 of the electrical connector of the present invention, such as Figure 1-6 As shown, the housing 11 is included. In this embodiment, the main part of the housing 11 is cylindrical and the rear end is provided with a mounting plate 111 for matching with the corresponding mounting panel. In addition, the housing 11 adopts a high-strength, Made of light-weight composite plastic, the housing 11 is equipped with a contact assembly, the contact assembly includes a glass insulator 12, the glass insulator 12 is a glass cake with holes, and the hole of the glass insulator 12 is equipped with a contact 13, the glass insulator The outside of 12 is covered with a metal sheath 14, and the three are sintered and fixed together after assembly. In other words, the metal sheath 14 and the contact piece 13 are sintered and fixed together through the glass insulator 12, forming a seamless connection between the three. With reliable sealing performance, the front end of the met...

Abstract

The invention relates to the field of an electric connector, in particular to a contact element component and a hermetic seal connector using the component. The electric connector comprises a housing and the contact element component assembled in the housing; the contact element component comprises a glass insulator, at least one contact element assembled in the glass insulator and a metallic sheath arranged outside the glass insulator; the contact element and the metallic sheath are sintered together through the glass insulator; the contact element component is fixedly assembled in the housing through the metallic sheath; and the metallic sheath is matched with the housing in a sealing manner. The electric connector is capable of preventing the housing from withstanding high temperature when the contact element is assembled, and simultaneously the glass insulator and the housing are not required to be sintered and the requirement of binding ability of housing material and glass is also reduced, so that the limitation to the heat resistance of the housing material of the electric connector and the binding property of glass is solved, a user can select a lighter material as the housing material according to requirements, and the problem that the existing electric connector is heavy in weight is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a contact assembly and a hermetic connector using the assembly. Background technique [0002] With the modular development of communication and other equipment, the application range of electrical connectors is also becoming wider and wider. In some occasions where the sealing performance of electrical connectors is required to be high, it is often required to withstand 1 atmospheric pressure (1.01×10 5 Pa) pressure, the leakage rate does not exceed 1.0×10 -3 Pacm 3 / s. In the current connector products, the ways to achieve hermeticity include potting adhesive structure, ceramic sealing structure and glass sealing structure. The potting adhesive structure exhibits lower mechanical strength (under 0.5 atmospheres) and higher gas leakage rate (leakage rate 0.46×10 2 Pacm 3 / S), and it is easy to volatilize harmful components at high temperature, so it is not suitable to b...
